Thanks to all for yours responses, My antivirus, up to date, didn't detect anything in the file. For more security, I removed the 3 links to "meteoblue and copernicus atmospheric depth predictions". Why is this (not very salesy) spreadsheet more interesting than a simulator image? First of all, the images used in other simulations are taken from cameras and don't really correspond to our brain's impressions and interpretations. Worse still, they often give us a far too optimistic picture. Secondly, this spreadsheet uses far more parameters than any other simulator I've seen: your visual performance, your equipment (including filters) and its precision, your atmospheric conditions. Finally, it gives advice on how to observe the planets according to your choices for the best view. Commercial example: depending on a customer's observation location (climate...), experience and equipment (or not) and preferred planets, it's possible to refine purchasing advice with this simulator. Then in the field: By setting the parameters of the spreadsheet with your own equipment, and the weather... you can find out if your equipment will perform well, how to get the most out of it, and virtually test additional equipment to see if it significantly enhances image quality, or not. Finally, you can use local ephemerides to predict the best configuration for your preferences. Thanks vlaiv, for your suggestions for improvement. I thought the instructions would be enough: It isn't. As for the video, I don't have a good English accent, so that'll come later. Simplifying the presentation is difficult but not impossible (there are millions of calculations in this sheet and when I copy-paste or cut-paste.... excel sometimes makes mistakes and it takes me several hours of checking to detect them). So I'll start by creating screens with comments on a few cases to help understand the file. see you soon Laurent PLANET COLOR 4-0 without links.xlsx

Hello everyone, For several years I've been working on a project to simulate the behavior of our eyes behind an eyepiece to understand which magnification to choose to see the chosen details on the chosen planet, with the chosen equipment and the chosen atmospheric conditions. I often got it wrong, rarely got the equations right, and used a lot of published material. I've included this work in the attachment, along with instructions to help you understand it progressively. I hope I haven't left any mistakes. I hope this file helps you in your choices. Rattini Laurent Warning: this excel file is based on a French configuration (see excel options -> verification -> language) where commas delimit the integer part of decimals in a number (example: PI=3,141592).
